PROBLEM TO BE SOLVED: To provide a stereo lithographic device capable of correcting a deviation of a laser emitting position while advancing a stereo lithographic method without interrupting time of a measurement or the like of a stereo lithographic product by automatically detecting a deviation amount of the emitting position and having good accuracy and efficiency. SOLUTION: A method for producing the stereo lithographic product comprises the steps of emitting a laser beam 8 from a laser beam generator 9 toward a measuring point 11 provided on a table 4, photographing the laser emitting position by a CCD camera 31, image processing the photographed image, detecting the emitting position by a position detection controller 32, comparing the detected laser emitting position with the position of the measuring point, calculating the deviation amount of the emitting position from the measuring point, obtaining a correcting value of the emitting position by a position correction controller 33, and instructing a scanner controller 23 so as to correct the emitting position to the position of the measuring point.
